How to find out if a user actually has Glass - google-mirror-api

I'm writing a fairly complicated application for Glass and I'm worried about users coming in, signing up, and using the resources for my AppEngine account even though they don't have Glass and will get no benefit from it. Is there currently any way in the Mirror API to actually determine if a user has Glass?

I think a way to verify they have Glass would be an excellent idea. This has been requested on the issues list.
In the mean time, you might want to implement "double opt-in". It is considered best practice to send a "welcome" card - you might want to extend that welcome card to tell them to acknowledge the card. This can be a fairly simple operation, and it isn't burdensome to either them or you. If they don't within some reasonable time frame (or after some reminders... or whatever), then you can probably disable your Glass activities to them.
Actually... the more I think about it, the more I like this idea even once our API quota limits are lifted...

Is there a way one can access the game time variables like health bar and other scores from a game running on unreal engine

My objective requires that I am able to access game time variables like health bar, certain scores etc, when the game is running. I do not want to change this variables, or cheat in the game in anyway, I just need to collect this data and do not want to modify it.
I need to be able to get that information in a python/c++ environment. I know that cheat engine like software might be able to help me, but since DRM and anti cheat software prevent me from doing just that and therefore it might not be possible anymore, other option I am currently exploring is to screengrab and using opencv and character recognition get the information I need visually, but this seems like unnecessary and extra work that might even not work that well.
I also explored if there is any API from unreal engine (the game is based on unreal engine) that might just allow me to do just this, but had no luck so far. So I ask you one more time, you to suggest me some solutions to this issue.
I think DOTA 2 allows this in some way, since openAI/others use data like this to train their AI's so it should be possible right!? I am just interested in knowing how can this be done.

Protecting (or tracking plagiarism of) Openly Available Web Content (database/list/addreses)

We have put together a very comprehensive database of retailers across the country with specific criteria. It took over a year of phone interviews, etc., to put together the list. The list is, of course, not openly available on our site to download as a flat file...that would be silly.
But all the content is searchable on the site via Google Maps. So theoretically with enough zip-code searches, someone could eventually grab all the retailer data. Of course, we don't want that since our whole model is to do the research and interviews required to compile this database and offer it to end-users for consumption on our site.
So we've come to the conclusion there isnt really any way to protect the data from being taken en-masse but a potentially competing website. But is there a way to watermark the data? Since the Lat/Lon is pre-calculated in our db, we dont need the address to be 100% correct. We're thinking of, say, replacing "1776 3rd St" with "1776 Third Street" or replacing standard characters with unicode replacements. This way, if we found this data exactly on a competing site, we'd know it was plagiarism. The downside is if users tried to cut-and-paste the modified addresses into their own instance of Google Maps -- in some cases the modification would make it difficult.
How have other websites with valuable openly-distributed content tackled this challenge? Any suggestions?
Thanks
It is a question of "openly distribute" vs "not openly distribute" if you ask me. If you really want to distribute it, you should acknowledge that someone can receive the data.
With certain kinds of data (media like photos, movies, etc) you can watermark or otherwise tamper with the data so it becomes trackable, but if your content is like yours that will become hard, and even harder to defend: if you use "third street" and someone else also uses it, do you think you can make a case against them? I highly doubt it.
The only steps I can think of is
Making it harder to get all the information. Hide it behind scripts and stuff instead of putting it on google maps, make sure it is as hard as you can make it for bots to get the information, limit the amount of results shown to one user, etc. This could very well mean your service is less attractive to the end user, this is a trade-off
Sort of the opposite of above: use somewhat the same technique to HIDE some of the data for the common user instead of showing it to them. This would be FAKE data, that a normal person shouldn't see. If these retailers show up at your competitors, you've caught them red-handed. This is certainly not fool-proof, as they can check their results for validity and remove your fake stuff, there is always a possibility a user with a strange system gets the fake data which makes your served content less correct, and lastly if your competitors' scraper looks too much like real user, it won't get the data.
provide 2-step info: in step one you get the "about" info, anyone can find that. In step 2, after you've confirmed that this is what the user wants, maybe a login, maybe just limited in requests etc, you give everything. So if the user searches for easy-to-reach retailers, first say in which area you have some, and show it 'roughly' on the map, and if they have chosen something, show them in a limited environment what the real info is.

Is it alright to track your users actions on the site for analytics purposes?

We use a tool that tracks individual users' mouse movements and clicks on our site. Right now it only tracks anonymous visitors, but we're thinking of using it to track specific logged in users' data. We'd be using it for analytics, but we'd like to have the data in case we need to analyze how a particular person uses the site.
Are people, in general, alright with this? Does this constitute privacy infringement?
The short answer is it is your site, for the most part (for now) you can track whatever you want on it.
However, some things to consider...
a) 3rd party analytics tools have their own privacy policies and Terms of Services that may or may not allow this, so if you are using something like Google Analytics, Omniture SiteCatalyst, WebTrends, Yahoo Web Analytics, etc.. then you need to read over their Privacy Policy and Terms of Service to make sure you are allowed to track this sort of thing. Offhand I don't think any of the ones I mentioned disallow tracking mouse movements/clicks specifically (and in fact, some of them have features/plugins for it, called "clickmap" tracking, or similar), but some do have restrictions on other data you may couple with this. For example, I know Google does not allow you to associate any data with the user's IP address. You cannot send it to GA in a custom variable, nor can you store it on your own server in any way that you can associate it with data you send to GA (for example, storing the user's IP in your own database along with a unique id, and then sending the unique id to GA, where you can then lookup IP by that unique id).
b) Privacy is indeed a concern that is currently being discussed by the powers-that-be, and your ability to track certain things may indeed be limited in the future. For now, it's mostly about personally identifiable information, and it's mostly happening in Europe, and tracking mouse movement/clicks generally isn't personally identifiable, but who knows what the future may bring.
c) Make sure you understand the costs involved in tracking mouse movements/clicks. In order to track something, a request has to be made, data sent somewhere. The more granular the data, the more requests and/or data needs to be sent. Whether it is your own baked up tracking solution on your own server or a 3rd party, this will cost something one way or the other. Imagine sending a request to a server for every x,y position of the mouse as it moves...this could quickly add up, and a lot of 3rd party solutions place a limit on how many requests can be made per visit(or) or day on an account.
d) On that note, if you are using a 3rd party solution, tracking something this granular may affect tracking more important stuff. As mentioned in "c", many 3rd party solutions limit how many requests can be made per visit(or) or day on your account, etc.. and if you hit the limit, any requests after that won't be tracked. Imagine if you have tracking on a sale confirmation page, tracking details about a sale made, which is very important tracking, being tossed out because of too many requests of mouse movements on some random page...
e) On that note... consider how actionable tracking mouse movements and clicks really is to you. This is a question you have to really ask yourself whenever you want to track something: "How actionable is this?" Basically, imagine yourself having the tracking in place and looking at the data...then what? What will you do with that data? Assuming the ultimate goal is to make more money, increase conversions on your site, etc.. do you really think knowing the paths a mouse cursor took on a given webpage will help you increase sales/conversions? How will you be able to know if the mouse movements are related to content on your page, or if they were just some random jerks/movements while reading content or making room on a desk, etc..? At best, the data will be polluted...
Clicks on links or specific action buttons on a page? Sure, those are certainly worth tracking. And most 3rd party solutions automatically track a lot of that stuff, or offer custom coding solutions for manual wiring up of things. And there are plenty of reports that can be made showing activity from them.

Why is the save button needed?

Software like OneNote has shown that auto-save can be implemented, and it works just as well (or better) as the manual save button / CTRL+S.
Anyways everything that you work on you want saved. Its just if you're trying out something destructive that you would close without saving.
So from a programmers/usability perspective, why is the manual "save" feature still seen in virtually all software today? Is it because everyone is too lazy to implement "auto-save" whenever data gets modified?
And is it a good idea for us implement auto-save, at least to start some traction in our specific industry and amongst our competitors?
autosave normally saves on a defined interval. What happens if you want to save in between intervals?
You should implement a manual save to stay consisent with other applications in the environment as well.
People expect file -> save, or CTRL + S to exist.
The save button is a well-known, comfortable UI feature that everyone from Jon Skeet to grandma is familiar with. If you got rid of it, it would be like removing the close button on a window for some people. Granted, they would eventually get used to it, but some people would not understand that their data has been saved automatically.
Also, if you're autosaving on the web, not only are you taking up a lot of space on your server with all those instances, you're also using up a lot of bandwidth with periodical saves. At least with manual save, you are only using the space and bandwidth when the user intends, which can be more infrequent, thus saving bandwidth. The advantage, of course, to autosaving is the retention of work should something go awry.
Check the definition of "skeuomorph" :)
Additionally with a "save" there is commonly "save as.." as well. Both give the user the feeling of control and security. Knowing that they clicked save lets them know at what state they can expect their data to be in when reloading it.
It really comes down to this: a Save button is cheaper to implement and maintain than Undo.
It is not hard to implement auto-save - just implement a normal save and call it when ever needed or just in a timer (if you are lazy).
Save buttons are common because of the common pattern learned by the users for decades.
Load data or files from a persistent storage into main memory.
Modify the data in main memory.
Save the modified data back to a persistent storage.
This pattern comes from the old distinction between harde drive and main memory. If you think about it in another way (as some experimental operating systems do), there is no need for loading and saving files - just think about a hard drive as your main memory and and the main memory as another cache level for the hard drive. In consequence all files (not on removeable medias) are always in memory and you will never again need to load or save files.
But doing this change is not easy because users are used to the old pattern for years. Further the old load and save pattern is an very easy way to get a kind of primitve undo system.
Auto-saving requires an undo system, too, and it is not that trivial to build one. Esspecialy if you perform image, audio or video editing and you are producing a lot of data it is hard to find a good time-memory-trade-off. And there is the risk that user will try to undo things by closing the application and then recognize that this did not work. So it might even be a good idea to persist undo information to protect users from this error or saving unwanted changes in the case of a crash.
So, yes, I would realy like to see the save (and load) buttons to disappear. I would like persisted undo-information or even complete edit histories, too. But I don't think this change can happen in a few years - if ever.
I work in the medical field and there are situations where you want the user to take responsibility for saving something. If you have an EHR and you are entering a prescription for a patient then you dont necessarily want it autosaving - you want the user to be aware of and take responsibility for their actions. Also, autosaving a value in a critical system like this could be disastrous for obvious reasons...
Should be tagged subjective maybe?
As a developer, I am always a little uneasy around apps like that. I like having control over when my data is saved, though perhaps this is just years of conditioning at work. I get that little "uh oh" feeling whenever I close a window into which I've entered data without explicitly pressing a close button (or shortcut).
That said, I have been "trained" to accept it in certain situations. OneNote, for example, or Tomboy. A great many OS X apps follow this pattern, especially utility apps like DB server GUI tools.
So, in short, different tools for different situations. IMO, most software these days would not benefit from a move from a manual save to an auto-save.
I think the answer to this is that 'it depends'!
You should consider not only your user's expectations in terms of consistency with other applications, but also the way in which the user is going to use your application.
A very common use-case for OneNote is that someone opens it up to dump in some information almost as an aside to what they're working on. They need to get in and out quickly. Any prompts about saving would be a nuisance.
Applications like Word, on the other hand, expect users to be spending a concerted amount of time working on a document. In this case, the chore of manually saving and responding to confirmation boxes etc will be seen as a relatively small task.
From programmers perspective implementing autosave would not be a huge deal. You just set up a timer and callback would do the saving.
However, from usability point of view autosave is very problematic. First of all users are used to having a manual saving and not offering it to them would confuse a majority of users and take feel of control away.
Even bigger issue would be that autosave overwrites contents of underlaying file whether you wanted it or not. Of course you could have autosave feature saving onto temporary file but the decision to overwrite original document must always come from the user, not from the software. And because you would anyways need the user to initiate at least one manual saving, why not enable manual saving to be available always?
An autosave feature is great when you are dealing with a document. What about a business application? If I edit a customer's account, should it update the account as I tab out of the edited fields? If so, what should it do when the account is in an invalid state? When do you enforce business rules and how do you enforce them? How will it perform when you have to take business rules into account on every edit?
You can certainly build an application that will take any of these considerations into account, but will it have been worth the extra effort?
So should we get rid of the Save button? It depends.
Short answer: "auto save" = "auto destroy" / "auto <expletive>".
For one project in university, my group and I built an application without explicit saving as an experiment.
We implemented an infinite undo stack and serialized the undo stack with the actual data so that even if you closed the app and re-opened it, you could always undo your last operation. Every operation wrote a new entry to the action list on disk so that the file was always consistent (well, mostly...), even if the power failed. It was a bit of a cross between a version control system and a journaling file system.
There were two problems: one, we didn't have time to get it completely right (ah, youthful hubris); two, everyone (fellow students and, most importantly, the TAs) hated it, because of all of the reasons mentioned already.
Sometimes, for all your best intentions, you just can't ignore ingrained behaviours.

Designing a main form ("main menu") for a WinForm application

The form that currently loads during when our beta WinForm application starts up is one that shows a vast array of buttons... "Inventory", "Customers", "Reports", etc. Nothing too exciting.
I usually begin UI by looking at similar software products to see how they get done, but as this is a corporate application, I really can't go downloading other corporate applications.
I'd love to give this form a bit of polish but I'm not really sure where to start. Any suggestions?
EDIT: I am trying to come up with multiple options to present to users, however, I'm drawing blanks as well. I can find a ton of design ideas for the web, but there really doesn't seem to be much for Windows form design.
I have found that given no option, users will have a hard time to say what they want. Once given an option, it's usually easier for them to find things to change. I would suggest making some paper sketches of potential user interfaces for you application. Then sit down with a few users and discuss around them. I would imagine that you would get more concrete ideas from the users that way.
Update
Just a couple of thoughts that may (or may not) help you get forward:
Don't get too hung up on the application being "corporate". Many coprorate applications that I have seen look so boring that I feel sorry for the users that need to see them for a good share of their day.
Look at your own favourite UI's and ask yourself why you like them.
While not getting stuck in the "corporate template", also do not get too creative; the users collected experience comes from other applications and it may be good if they can guess how things work without training.
Don't forget to take in inspiration from web sites that you find appealing and easy to use.
Try to find a logical "flow"; visualize things having the same conceptual functionality in a consistent way; this also helps the user do successful "guesswork".
You might look to other applications that your users are familiar with. Outlook is ubiquitous in my company, and we were able to map our application to its interface relatively easily, so we used that application as a model when developing our UI.
Note that I'm not suggesting Outlook specifically to you, just that you look for UIs that would make your users' learning curve shallower.
The problem here is that you need some good user analysis and I'm guessing you've only done functional analysis.
Because your problem is so abstract, it's hard to give one good example of what you need to do. I'd go to usability.gov and check out the usability methods link, especially card sorting and contextual interviews.
Basically you want to do two things:
1- Discover where your users think how information is grouped on the page: This will help flesh out your functional requirements too. Once you've got information all grouped up, you've basically got your navigation metaphor set up. Also, you can continually do card sorting exercises right down to page and function levels - e.g. you do one card sorting session to understand user needs, then you take one group of cards and ask users to break that down into ranks of importance. Doing so will help you understand what needs to be in dominate areas of the screen and what can be hidden.
2- Understand what tools they already use: what they do and don't like about them. You need to get a list of tools/applications that they use externally and internally. Internally is probably the most important because there is a fair chance that most people in your business will share an experience of using it. External tools however might help give you context into how your users think.
Also, don't be afraid to get pencil and paper and sketch up ideas with users. People generally understand that sketches are a quick and useful way to help with early design work and you can get an immense amount of information out of them with just simple sketches. Yes, even do this if you suck at sketching - chances are it won't matter. In fact, crappy sketches could even work in your favour because then nobody is going to argue if buttons should be blue, red or whatever.
Frankly, a form with a “vast array of buttons” needs more than a little polish. A form dedicated solely to navigation generally means you’re giving your users unnecessary work. Provide a pulldown or sidebar menu on each form for navigating to any form.
The work area of your starting form should provide users with something to actually accomplish their tasks. Among the options are:
A “dashboard” main form, showing summarized information about the users’ work (e.g., list of accounts to review and status of each, number of orders at each stage of processing, To Do schedule). Ideally, users should be able to perform their most common tasks directly in the opening form (e.g., mark each account as “approved” or not). If further information is necessary to complete a task, links navigate to detailed forms filled with the proper query results. At the very least users should be able to assess the status of their work without going any further. Note that different groups of users may need different things on their respective dashboards.
Default form or forms. Users of a corporate application typically have specific assignments, often involving only one to three of all your forms. Users who work with Inventory, for example, may almost never need to look at Customer records, and vice versa. Users also often work on a specific subset of records. Each sales rep, for example may be assigned a small portion of the total number of customers in the database. Divide your users into groups based on the forms and records they usually use. For each user group, start the app by automatically opening the user group’s form(s) populated with the query results of their records. Users should be able to complete most of their work without any further navigation or querying.
If all else fails, open the app to whatever forms and content were last open when the user quit the app. Many corporate users will continue to work tomorrow on the same or similar stuff they’re working on today.
Analyze the tasks of your users to determine which of the above options to use. It is generally not productive to describe each option to the users and ask which they like better.
BTW, “Reports” is probably not a particularly good navigation option. It’s better if you consistently identify things primarily by what they show, rather than how they show it. Users may not know that the information they want to see is in a “report” rather than a form, but they’ll know what content they want to see. Reports on inventory are accessed under Inventory; reports about sales are accessed under Sales.
Have you tried asking your end users what they would like? After all they are the ones that are going to be using the system.
I use components from the company DevExpress. They have some really cool controls (such as the Office 2007 ribbon), form skinning utilities (with a vast amount of different skins), and a load more...
If you want to check it out they have 60 free components - if its corporate though you might have to check the licence but you can get it at... DevExpress 60 Free
I suggest starting with the design principles suggested by Microsoft: Windows User Experience Interaction Guidelines
Some places to get ideas for interaction designs:
Books
About Face 3 - The Essentials of Interaction Design
Don't Make Me Think (this is focused on web design, but many of the principles carry over to Windows design)
Web Sites
Windows User Experience Interaction Guidelines
In addition, many applications have free trial versions that you can download to determine how they handle user interaction. Also, don't discount items on your desktop right now.
Do you have any statistics or insights concerning what the most commonly-used or important functions might be? If so, you could use that to pare down your "vast array of buttons" and highlight only those that are most important.
That's sort of a trivial example, but the underlying point is that your understanding of your audience should inform your design, at least from a functional perspective. You might have past usage statistics, or user stories, or documented workflows, or whatever - even if you're drawing a blank right now, remember that you have to know something about your users, otherwise you wouldn't be able to write software for them.
Building on what they already know can make it easy on your users. Do they live in Outlook? Then you might want to mimic that (as Michael Petrotta suggested). Do they typically do the same thing (within a given role) every time they use the app? Then look for a simple, streamlined interface. Are they power users? Then they'll likely want to be able to tweak and customize the interface. Maybe you even have different menu forms for different user roles.
At this stage, I wouldn't worry about getting it right; just relax and put something out there. It almost doesn't matter what you design, because if you have engaged users and you give them the option, they're going to want to change something (everything?) anyway. ;-)
